I have a 99 Ford V-10, class C,28.5'
I have towed with a Jeep truck, with a 304, a Car hauler with a 454 pulling a pop up, a Ford E-250 with a 460 a 72 Dodge Class A with a 440,
The V-10 E450 chassis, does better than any of the rest. Most of them done Speed limit no trouble. The hills were the only issue. Just took a little more time to pull them.
Old Fort Mnt is my hardest hill I have climbed, but some of the hills going to Harlan are tough too. As long as I don't have to lift the pedal I can top Old Fort at 42-45 mph. The flats are easy though, 65-80, is no issue.
It pulls good. I have a 6K Jeep, and a 2K trailer. I run 60 lbs, in the air bags, and it handles just fine. To me, the van front end makes driving easier than with a class A.
The only time I have checked the fuel mileage is after pulling all the big hills, going to Harlan, at the first fuel stop. Which takes about a half of tank. Usually around 6.75 or so.
I run all synthetic lubes.
For me, it has worked out just fine, and I would own another with similar set up.
